Full frame sized imageLenses that create APS-C sized image are designed for digital only. They cannot be used on cameras that have image sensor larger than the APS-C format. These lenses are not suitable for film cameras either. No Ultrasonic AFLenses with ultrasonic focusing mechanism tend to be quiter and faster than traditionally focusing lenses. No stepping motor AFLenses with stepping motor focusing mechanism are better for contrast based focusing, and are quiter and faster than traditionally focusing lenses. No Low Dispersion lens element is usedLow Dispersion lens elements help to reduce chromatic aberration. Not stabilizedImage stabilization helps to reduce blur caused by hand shake, especially at high focal length or in low light situations. Image stabilization can give 1 to 3 stop advantage over none stabilized lens, based on the reciprocal rule. Internal FocusingInternally focusing lenses don't change their size while setting focus. |

The smc FA Zoom 28mm~105mm f/4~f/5.6 standard zoom lens is an ideal lens for portraiture photography. It provides a focal length range from 28mm wide angle to 105mm telephoto, and an internal focusing system for faster and smoother focusing. Like all PENTAX lenses, the FA Zoom 28mm~105mm f/4~f/5.6 features smc coating to maximize light transmission and produce sharp, high-contrast images while minimizing flare and ghost imaging.
